The Sea-Crossing Temburong Bridge in Brunei is about 30 kilometers long across the Brunei Bay, and it is the largest infrastructure project in Brunei, linking Muara District and Temburong District across the sea. The 11.8-kilometer-long CC4 section constructed by CSCEC is divided into upper and lower double spans, with a total of more than 1,990 spans, all of which are prefabricated structures and specifically implemented by China Construction Sixth Engineering Division Corp. Ltd.. In 2019, the project's safe construction exceeded 8 million man-hours and won International Safety Awards from the British Safety Council.
